Name the following compound, BrF\u2085<\/strong><br><strong>Correct answer: a. Bromine pentafluoride<\/strong><\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>BrF\u2085 is a binary molecular compound consisting of a nonmetal (bromine) and another nonmetal (fluorine). The naming rules for such compounds involve using Greek prefixes to denote the number of atoms of each element and naming the more electronegative element (fluorine) last with the &#8220;-ide&#8221; suffix. &#8220;Br&#8221; is bromine and &#8220;F&#8221; is fluorine, with five fluorine atoms. Therefore, the correct name is <strong>bromine pentafluoride<\/strong>.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Option <strong>b<\/strong> (\u201cbromine fluoride\u201d) is incomplete because it doesn&#8217;t indicate the number of fluorine atoms.<\/li>\n\n\n\n<li>Option <strong>c<\/strong> (\u201cbromine (IV) fluoride\u201d) uses ionic nomenclature, which is not appropriate for this covalent compound.<\/li>\n\n\n\n<li>Option <strong>d<\/strong> (\u201cmonobromine pentafluoride\u201d) is incorrect because the prefix \u201cmono-\u201d is generally omitted for the first element when there is only one atom.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>10. What is the name of the acid HSCN?<\/strong><br><strong>Correct answer: b. Hydrothiocyanic acid<\/strong><\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>HSCN is the chemical formula for <strong>hydrothiocyanic acid<\/strong>. It is a derivative of thiocyanate (SCN\u207b) and behaves similarly to hydrocyanic acid (HCN), but with a sulfur atom replacing the oxygen in the corresponding oxyacid family.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Option <strong>a<\/strong>, hydrocyanic acid, refers to HCN, not HSCN.<\/li>\n\n\n\n<li>Option <strong>c<\/strong>, thiocyanic acid, would be a less systematic name and could confuse with isomers.<\/li>\n\n\n\n<li>Option <strong>d<\/strong> is incorrect because HSCN is a known and real compound.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>11. What is the chemical formula for copper (II) hydroxide?<\/strong><br><strong>Correct answer: d. Cu(OH)\u2082<\/strong><\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>Copper (II) means copper has a +2 charge (Cu\u00b2\u207a). Hydroxide (OH\u207b) has a -1 charge. To balance the +2 charge from one Cu\u00b2\u207a, two OH\u207b ions are needed:<br><strong>Cu\u00b2\u207a + 2OH\u207b \u2192 Cu(OH)\u2082<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Option <strong>a<\/strong>, Cu\u2082(OH), suggests incorrect stoichiometry.<\/li>\n\n\n\n<li>Option <strong>b<\/strong> and <strong>c<\/strong>, CuOH and CuOH\u2082, don\u2019t correctly represent the 2:1 ratio.<br>Therefore, the only correct formula is <strong>Cu(OH)\u2082<\/strong>, a blue solid base.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/05\/learnexams-banner5-153.jpeg\" alt=\"\" class=\"wp-image-222181\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>.
